Affiliate disclosure

Health Britannica is reader-supported. When you buy through links on our site, we may earn an affiliate commission at no additional cost to you. This helps us keep all content free and independent.

How it works

Many of the product links on Health Britannica are affiliate links. When you click one and make a purchase, the retailer pays us a small commission (typically 3-10% of the sale price). This never increases the price you pay.

What this means for our reviews

Our editorial ratings and recommendations are never influenced by affiliate relationships. Our 6 proposition value scoring system is applied identically regardless of whether a product has an affiliate program. We frequently recommend products and brands that:

• Pay lower commissions than alternatives
• Have no affiliate program at all
• Are budget options when premium alternatives would earn us more

Affiliate partners

We participate in, or are in the process of joining, the following affiliate programs:

• Direct brand programs, partnerships with supplement brands and retailers we recommend, via each brand's own affiliate program
